At 8 am (Eastern/Pacific) on Tuesday, and repeating at 2 pm, History Channel is showing "Empires of Industry: Battle for the Skies". The program follows the path of TWA and Pan Am, among others. Has anyone seen this? Below is the synopsis.

Air travel has all but obliterated time and distance. Journeys once measured in weeks now take hours. It's an amazing accomplishment: a multi-billion dollar industry that changed the world within the span of a lifetime--or actually two. Follow the lives of two men who dominated the rise of international air travel: Juan Trippe, whose Pan American Airways practically created the industry, and eccentric tycoon Howard Hughes, who built TWA.
